We divide 49449489 by 639
We want to figure out the number of times 49449489 can be divided by 639.

Advancing to step 1:
4 divided by 639 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 639

Moving on to step 2:
If we divide 49 by 639, we get 0 and a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Fetch the next digit (4) from the dividend, attach it to 49 and continue: 494 / 639

Step 3:
639 can be fit into 494 0 times, resulting in a remainder of 494.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 494, we get 494.
Fetch the next digit (4) from the dividend, attach it to 494 and continue: 4944 / 639

Moving on to step 4:
639 goes into 4944 7 times with a remainder of 471.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 4473 away from 4944, we end up with 471.
Grab the next digit (9) from the dividend, add it to 471, then carry on: 4719 / 639

Moving on to step 5:
When dividing 4719 by 639, we get 7 with a remainder of 246.
Put 7 as the next digit of the answer. 
Result so far: 77.0
The remainder is 246 after subtracting 4473 from 4719.
Grab the next digit (4) from the dividend, add it to 246, then carry on: 2464 / 639

Let's proceed to step 6:
If we divide 2464 by 639, we get 3 and a remainder of 547.
Put 3 as the next digit of the answer. 
Result so far: 773.0
The remainder is 547 after subtracting 1917 from 2464.
Include the next digit (8) from the dividend after 547, then repeat: 5478 / 639

Moving on to step 7:
If we divide 5478 by 639, we get 8 and a remainder of 366.
Use 8 as the next digit of our solution. 
Result so far: 7738.0
Deduct 5112 from 5478 and we're left with 366.
Bring next digit (9) of the dividend behind the 366 and repeat the process: 3669 / 639

Moving on to step 8:
If we divide 3669 by 639, we get 5 and a remainder of 474.
The number 5 becomes the next digit in our result. 
Result so far: 77385.0
Subtracting 3195 from 3669 leaves us with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Going ahead to step 9:
When dividing 4740 by 639, we get 7 with a remainder of 267.
The number 7 becomes the next digit in our result. 
Result so far: 77385.7
Subtracting 4473 from 4740 leaves us with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

On to step 10:
If we divide 2670 by 639, we get 4 and a remainder of 114.
The number 4 becomes the next digit in our result. 
Result so far: 77385.74
Deduct 2556 from 2670 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 11:
If we divide 1140 by 639, we get 1 and a remainder of 501.
Put 1 as the next digit of the answer. 
Result so far: 77385.741
Subtracting 639 from 1140 leaves us with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Step 12:
5010 divided by 639 is 7 with a remainder of 537.
Write down 7 as next digit of the result. 
Result so far: 77385.7417
The remainder is 537 after subtracting 4473 from 5010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Step 13:
639 goes into 5370 8 times with a remainder of 258.
The next digit of our result is 8. 
Result so far: 77385.74178
If we take 5112 away from 5370, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 14:
639 goes into 2580 4 times with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 77385.741784
If we take 2556 away from 2580, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 15:
The number 639 fits into 240 0 times, leaving a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 77385.741784
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 16:
When dividing 2400 by 639, we get 3 with a remainder of 483.
The number 3 becomes the next digit in our result. 
Result so far: 77385.74178403
Deduct 1917 from 2400 and we're left with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

After the division, we end up with 77385.74178403 and a remainder of 4.83e-07.
